Can a Fish Drown Itself?

Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don't technically drown, because they don't inhale the water, but they do die from a lack of oxygen.

Can fish drown themselves?

Fish are physically incapable of drowning because they have gills, not lungs. They can die if there's not enough dissolved oxygen in the water which would make them suffocate, technically. So, if you've wondered can fish drown, the answer is no.

How long does it take to drown a fish?

They can suffocate and die quickly without water (following three to four minutes of no gill movement), so it's important that you don't take them out unless the new water is ready for their transfer.
